xNodes are the third generation of light, half-rack, high-performance IP-Audio interfaces from Axia. They’re loaded with advanced features and capabilities. One-button configuration takes a new xNode from out-of-the-box to on-the-air in under one minute. They’re fanless, which means they’re noiseless too. They have a versatile mounting arrangement that lets you deploy two xNodes in just 1RU of rack space, as well as by themselves on ceilings, walls or under counters with the available wall-mount kit. They’ve got studio-grade audio performance specs. And they even have managed power options (via AC mains or Ethernet PoE) and dual network interfaces for redundant operation.
xNodes are available in Analog, AES/EBU, Microphone-level, Mixed-Signal and GPIO versions to handle virtually any signal encountered in today’s broadcast studio.
World's first AES67-compatible broadcast product! xNodes can connect to and interchange audio with any manufacturer's AES67-compatible broadcast device.
Fanless design with heavy cast-aluminum heat-sinks is completely silent in-studio. Front-panel heat sinks are cooled by ambient air, not “rack air,” eliminating overheating worries.
High-resolution front-panel multi-function OLED display meters inputs and outputs or GPIO status, gives software and other status information.
xNodes feature redundant power with auto-switching. Multi-color LED indicator glows green when AC mains power is present, red when running on PoE, and orange when both AC and PoE are connected.
Redundant power plan lets xNodes run on AC or Power over Ethernet (IEEE 802.3af) supplied by compliant Ethernet switches (such as Axia xSwitch and QOR integrated console engines). xNode will run on either power supply; connect both for redundant power with automatic switchover.
Power-efficient: xNodes use just 14 Watts each.
Network connection has backup, too: dual NICs allow you to connect xNode to separate network branches for full audio pathway redundancy. Automatic failover activates backup connection should the primary be interrupted.
Built-in Syslog server with configurable event filter and SNMP (Simple Network Management Protocol) support help you stay fully informed, should an xNode’s power or connection status change.
Synchronize your AES master clock to a designated xNode AES/EBU input to keep all of your AES streams synchronized to the house clock.
xNodes use premium components: rugged cast aluminum faceplates and heat sinks, high-resolution OLED displays, bulletproof power supplies designed for high-availibility telecom applications, studio-quality SRCs with recording-studio specs.
I/O connections via industry-standard RJ-45 audio connectors or high-density DB-25 connections, both available prefabricated and ready to attach in seconds.
Versatile mouting options: use freestanding, rack singly or side-by-side, or wall-mount using an accessory surface-mount kit.
Analog xNodes can be configured to create 4 stereo audio channels for your network to use, or 8 true mono channels. They can also receive 4 stereo or 8 mono channels, and send them to its outputs. This option is easily selectable in software via the built-in Web interface.
The Power of the Network.
One day, all audio equipment will be networked. Until then, there are xNodes, the world's first self-configuring AoIP interfaces.
xNodes give you an easy way to add non-networked audio devices to your studio network. And they pack a lot of I/O into a very small space. xNodes nearly configure themselves. Just plug them in and they go to work, configuring channel numbers and even signal names (editable by you) all by themselves. In just moments, you're ready to start sending and receiving network audio.
All xNodes feature a high-resolution OLED front panel display and two “soft” buttons to provide status information and assist with initial setup, and a multi-color LED that gives at-a-glance information about the xNode’s power configuration. To ensure ultra-reliable network operations and extremely low delay, xNodes run Linux on an embedded processor, and a built-in web server in each node gives you remote configuration and control – in an intuitive, easy-to-understand manner – using any standard Web browser.
xNodes are loaded with features designed to ensure the uptime of your network. Dual Ethernet ports can provide redundant connections to separate network segments. Redundant power capability with automatic switchover enables xNodes to run on house mains or PoE (Power over Ethernet), letting the network switch itself supply power, and enabling easy single-cable setup in places where ACpower isn’t practical. Built-in Syslog servers with a configurable event filter and SNMP (Simple Network Management Protocol) support let you stay fully informed, should an xNode’s power or connection status change.
xNodes are convenient, too. For example, a Microphone xNode placed in a studio can take audio from microphones and also provide outputs to associated studio monitors and headphones. An xNode in the rack room can collect audio from network feeds, codecs and other shared sources for system-wide use while providing handy outputs for audio processors and other terminal-room gear.
xNodes are easy to deploy — easier than any other AoIP interface. When you connect an xNode to your network, it automatically prompts you to give it an ID via the front-panel controls. Then, it derives a unique static IP address, and even gives names to its sources and outputs (which you can edit later, from the comfort of your computer). All you have to do is connect devices to the inputs, and it advertises that its audio sources are available for use, allowing any users access to them.
xNodes provide superior audio quality. Not only are they capable of operating at a network sampling rate of 48 kHz, they also employ high-resolution 32-bit floating-point SRC chips. xNodes produce a “sweeter,” more natural audio quality — clients routinely tell us of noticeable sonic improvements after the installation of their Axia network.
xNodes are easy to deploy, too. They’re fanless, so you can tuck one anywhere you need I/O. They’re compact: two xNodes fit side-byside in a single rack space using a simple rack-mount kit. Or, mount them to walls, ceilings, under countertops, using the optional surface-mount kit.
5 different xNodes provide analog and AES ins and outs, microphone inputs and GPIO logic ports, wherever you need them. No need for “home runs” to a central rack – one CAT-5 cable connection is all an xNode needs to interface multiple channels of bi-directional audio to your network.
The Microphone xNode has four professional-grade microphone preamps with selectable Phantom power and software-adjustable gain. There are also four balanced analog line outputs to conveniently deliver headphone and studio monitor feeds back to your talent. Inputs and outputs are presented both on easy-to-install RJ-45s and high-density DB-25s, both of which connect to easily available 3rd-party breakout cables, to suit your connection preference.
The Analog xNode has 8 mono or 4 stereo balanced line-level inputs and 8 mono or 4 stereo balanced line-level outputs, on RJ-45 and DB-25 connectors. Each input is switchable to accomodate either consumer-level -10dBv or professional level +4dBu sources. The short-circuit protected outputs can deliver up to +24dBu before clipping. Axia uses only studio-grade A/D/A converters and low-noise components, so that each Analog node provides superior audio performance for high-end studio use.
Our AES/EBU xNode has 4 AES/EBU inputs and 4 AES/EBU outputs. Left and right inputs signals may be split and routed independently as mono signals. Stunning performance specs include 48 kHz sampling rate, 126 dB of dynamic range, and ,0.0003% THD. Sample rate conversion is available on all inputs; the unit an also be synchronized to a house clock to provide sync to your entire Axia network.
The Mixed-Signal xNode is your utility player; perfect for places that require a mix of different audio I/O types. It provides 1 selectable Mic/Line analog input, 2 dedicated analog line inputs, 3 analog line outputs, 1 digital AES3 input and 1 AES3 output, and 2 GPIO ports -- truly a "jack of all trades."
GPIO xNode provides 6 general-purpose logic ports for machine control of studio peripherals -- audio devices, loudspeaker muting relays, signal lamps, etc. -- each with 5 opto-isolated inputs and 5 outputs. A logic port can be associated with any audio input or output and routes control data transparently along with the audio.
